Abstract
A coin acceptor includes first and second members initially spaced apart from one another and frictionally carrying a third member having a coin selectively positioned thereon. Moving the first and second members toward one another causes relative displacement between the third member and the first and second members. The relative displacement is compared with a reference position.
